Caffeine
Open SourceFundedHigh performance, near optimal caching library for Java applications
About Caffeine
Caffeine is an advanced, high-performance caching library designed for Java applications, providing in-memory caching capabilities that optimize data retrieval and improve application responsiveness. It is inspired by Google Guava's cache but offers enhanced features such as size-based eviction, time-based expiration, asynchronous refresh, and automatic loading of cache entries. The library supports weak and soft references for keys and values, allowing efficient memory management and preventing memory leaks.
Targeted primarily at enterprise Java developers and architects, Caffeine enables the creation of flexible, scalable caching solutions that reduce database load and latency. Its API is designed for ease of integration with existing Java applications, making it suitable for large-scale systems requiring robust caching mechanisms. The library's ability to accumulate cache access statistics and notify on evictions further supports performance tuning and monitoring in complex environments.
